Description
Engin motorisé de recyclage d'agrégats et ensemble motorisé pour la réalisation de tranchées comportant un tel engin motorisé Motorized aggregate recycling machine and motorized assembly for making trenches comprising such a motorized machine
La présente invention concerne un engin motorisé de recyclage d'agrégats, ainsi qu'un ensemble motorisé pour la réalisation de tranchées dans le sol, qui comporte un tel engin motorisé de recyclage d'agrégats. The present invention relates to a motorized machine for recycling aggregates, and a motorized assembly for making trenches in the ground, which comprises such a motorized machine for recycling aggregates.
L'ensemble motorisé pour la réalisation de tranchées dans le sol, a pour fonction de réaliser des tranchées pour la pose d'objets allongés tels que, par exemple, des câbles optiques et/ou électriques, des canalisations et/ou conduites flexibles, ... The motorized assembly for producing trenches in the ground, has the function of making trenches for laying elongated objects such as, for example, optical and / or electrical cables, pipes and / or flexible pipes,. ..
Généralement, la réalisation d'une telle tranchée dans le sol, qui peut être la chaussée ou l'accotement d'une route ou analogue, s'effectue par un dispositif de creusage à roue trancheuse porté par un engin motorisé spécifique. Pour réduire la durée des travaux du fait de la gêne occasionnée par ceux-ci, un autre engin est souvent utilisé pour aspirer et récupérer les agrégats produits lors du creusage de la tranchée en sortie du front de taille de la roue trancheuse. Generally, the realization of such a trench in the ground, which may be the roadway or the shoulder of a road or the like, is performed by a trencher wheel digging device carried by a specific motorized vehicle. To reduce the duration of the work due to the inconvenience caused by them, another machine is often used to suck up and recover the aggregates produced during the digging of the trench at the output of the cutting wheel face size.
Par le brevet FR-2 822 862, on connaît un véhicule qui assure simultanément les deux fonctions de creusage de la tranchée et d'aspiration (et de collecte) des agrégats, ce qui permet, en condition de travail, de réduire considérablement la gêne occasionnée lors de l'exécution des travaux sur le réseau routier et de diminuer également la logistique engagée et, donc, les coûts de réalisation. Patent FR-2 822 862 discloses a vehicle which simultaneously provides the two digging functions of the trench and suction (and collection) aggregates, which allows, in working condition, to significantly reduce the inconvenience caused during the execution of the works on the road network and to decrease also the engaged logistics and, thus, the costs of realization.
Toutefois, pour un tel chantier de réalisation de tranchée ou pour tout autre chantier pour lequel des agrégats sont générés, se pose toujours la question de l'évacuation des agrégats du chantier, puis de leur traitement, recyclage ou stockage. However, for such a trench construction site or for any other site for which aggregates are generated, there is always the question of the removal of aggregates from the site, and then their treatment, recycling or storage.
Ces opérations présentent des coûts (logistiques et de main d'œuvre) non négligeables.
La présente invention a pour objet de remédier à ces inconvénients. Elle concerne un engin motorisé de recyclage d'agrégats, comprenant un châssis et une unité motrice. These operations have significant costs (logistics and labor). The present invention aims to overcome these disadvantages. It relates to a motorized machine for recycling aggregates, comprising a frame and a power unit.
A cet effet, selon l'invention, ledit engin motorisé comporte, montés sur le châssis : For this purpose, according to the invention, said motorized device comprises, mounted on the chassis:
- un dispositif de collecte des agrégats ; - a device for collecting aggregates;
- une chambre de concassage alimentée en agrégats par ledit dispositif de collecte d'agrégats, et configurée pour concasser les agrégats et pour fournir des agrégats concassés à une sortie ; a crushing chamber fed with aggregates by said aggregate collecting device, and configured to crush the aggregates and to provide crushed aggregates at an outlet;

- de collecter sur un chantier, par exemple sur un chantier de creusage de tranchées, les agrégats produits ; et - to collect on a site, for example on a trenching site, the aggregates produced; and
- de les transformer en mortier qui est utilisé directement sur le chantier, par exemple pour reboucher une tranchée préalablement formée dans le cas d'un chantier de creusage de tranchées, après la pose dans la tranchée creusée d'objets allongés tels que des câbles par exemple. - turn them into a mortar that is used directly on the site, for example to fill a trench previously formed in the case of a trenching site, after laying in the trench dug elongated objects such as cables by example.
La présente invention permet donc un recyclage efficace, directement sur le chantier, de l'ensemble des agrégats produits, et ceci à l'aide d'un seul et même engin motorisé, ce qui permet d'une part d'éviter les coûts usuels d'évacuation d'agrégats et d'autre part de disposer de mortier (auto- compactant, fluide, homogène et stable) prêt à l'emploi sur le chantier.

Conformément à l'invention, l'engin motorisé 1 représenté sur les figures 1 et 2 est un engin mobile de recyclage d'agrégats. Cet engin motorisé 1 comprend un châssis 2 d'axe longitudinal L et une unité motrice 3 associée à quatre essieux munis de roues 4 pour générer le déplacement de l'engin motorisé 1 sur le sol, dans le sens illustré par une flèche E sur la figure 1 . Sur les figures 1 et 2, la cabine de conducteur 5 est représentée très schématiquement. According to the invention, the motorized vehicle 1 shown in Figures 1 and 2 is a mobile machine for recycling aggregates. This motorized vehicle 1 comprises a chassis 2 of longitudinal axis L and a power unit 3 associated with four axles provided with wheels 4 to generate the movement of the motorized vehicle 1 on the ground, in the direction illustrated by an arrow E on the figure 1 . In Figures 1 and 2, the driver's cab 5 is shown very schematically.
Selon l'invention, ledit engin motorisé 1 comporte une chaîne de traitement 6 qui est montée sur le châssis 2. Cette chaîne de traitement 6 comprend, montés sur le châssis 2 de l'avant 13A vers l'arrière 13B du châssis 2 : According to the invention, said motorized vehicle 1 comprises a processing chain 6 which is mounted on the chassis 2. This processing chain 6 comprises, mounted on the chassis 2 from the front 13A to the rear 13B of the chassis 2:
- un dispositif de collecte 7 configuré pour amener les agrégats dans la chaîne de traitement 6. Sur les figures 1 et 2, on a représenté une partie d'un tuyau (ou conduite souple) 8 du dispositif de collecte 7, par lequel sont récupérés les agrégats qui sont généralement disponibles au niveau du sol, devant ou à côté de l'engin motorisé 1 . Dans une application préférée, décrite ci-dessous, les agrégats sont extraits de la chaussée ou accotement par une roue
trancheuse qui, elle-même, est carénée afin que les agrégats soient plus facilement collectés et prennent un flux d'aspiration vers une chambre de concassage 9 ; a collection device 7 configured to bring the aggregates into the processing line 6. In FIGS. 1 and 2, a portion of a pipe (or flexible pipe) 8 of the collecting device 7, by which are recovered, is shown. aggregates that are generally available at ground level in front of or beside the motorized vehicle 1. In a preferred application, described below, the aggregates are extracted from the pavement or shoulder by a wheel slicer which, itself, is careened so that the aggregates are more easily collected and take a suction flow to a crushing chamber 9;
- la chambre de concassage 9 alimentée en agrégats par ledit dispositif de collecte 7, et configurée pour concasser les agrégats reçus et pour fournir des agrégats concassés à une sortie ; the crushing chamber 9 supplied with aggregates by said collecting device 7, and configured to crush the aggregates received and to provide crushed aggregates at an outlet;
- un dispositif mélangeur 10 lié de la manière précisée ci-dessous à la chambre de concassage 9 de manière à recevoir au moins une partie des agrégats concassés (calibrés) disponibles à la sortie de la chambre de concassage 9. Ce dispositif mélangeur 10 est configuré pour mélanger les agrégats concassés reçus, avec au moins un liant (ou du ciment) et de l'eau disponibles dans des cuves localisées par une flèche 1 1 , afin de produire un mortier ; et a mixing device 10 connected in the manner specified below to the crushing chamber 9 so as to receive at least a portion of the crushed aggregates (calibrated) available at the outlet of the crushing chamber 9. This mixing device 10 is configured for mixing the crushed aggregates received, with at least one binder (or cement) and water available in tanks located by an arrow 1 1, to produce a mortar; and
- une voie de distribution 12 configurée pour distribuer (c'est-à-dire pour fournir) le mortier produit en sortie du dispositif mélangeur 10, à l'arrière 13B de l'engin motorisé 1 . a distribution channel 12 configured to dispense (that is to say, supply) the mortar produced at the outlet of the mixing device 10, at the rear 13B of the motorized machine 1.
Ainsi, l'engin motorisé 1 permet à la fois : Thus, the motorized vehicle 1 allows both:
- de collecter sur un chantier les agrégats qui sont produits ou disponibles sur ce chantier ; et - to collect on a site the aggregates that are produced or available on this site; and
- de les transformer en mortier qui est utilisé directement sur ledit chantier. - turn them into a mortar that is used directly on the site.
La présente invention permet donc un recyclage efficace directement sur le chantier de l'ensemble des agrégats produits, et ceci à l'aide d'un seul et même engin motorisé 1 . The present invention thus allows effective recycling directly on the site of all the aggregates produced, and this with the aid of a single motorized vehicle 1.
Dans un mode de réalisation préféré, représenté sur les figures 1 et 2, l'engin motorisé 1 comporte également un crible 14. Ce crible 14 est agencé entre la chambre de concassage 9 et le dispositif mélangeur 10. In a preferred embodiment, shown in Figures 1 and 2, the motorized vehicle 1 also comprises a screen 14. This screen 14 is arranged between the crushing chamber 9 and the mixing device 10.
Le crible 14 est configuré pour séparer les agrégats disponibles en sortie de la chambre de concassage 9 en fonction d'une taille prédéterminée. Les agrégats dont la taille est inférieure ou égale à ladite taille prédéterminée, sont transmis au dispositif mélangeur 10 via une voie de transfert 15 dont une extrémité 15A débouche, par exemple, au-dessus d'une rampe 26 permettant
aux agrégats concassés d'accéder dans des cuves 17 et 18 du dispositif mélangeur 10, comme illustré schématiquement par des flèches A1 à A4 sur la figure 3. Les agrégats dont la taille est supérieure à ladite taille prédéterminée sont, quant à eux, renvoyés dans la chambre de concassage 9. The screen 14 is configured to separate the aggregates available at the outlet of the crushing chamber 9 according to a predetermined size. Aggregates whose size is less than or equal to said predetermined size, are transmitted to the mixing device 10 via a transfer path 15, one end 15A opens, for example, above a ramp 26 allowing to the crushed aggregates access to tanks 17 and 18 of the mixing device 10, as schematically illustrated by arrows A1 to A4 in Figure 3. The aggregates whose size is greater than said predetermined size are, in turn, returned to the crushing chamber 9.
Pour le transfert d'agrégats d'une unité à une autre à l'intérieur de la chaîne de traitement 6, l'engin motorisé 1 comporte des voies de transfert 15 et 19 qui peuvent être réalisées de différentes manières usuelles. Elles peuvent comporter, par exemple, un tapis roulant. For the transfer of aggregates from one unit to another within the processing line 6, the motorized vehicle 1 comprises transfer channels 15 and 19 which can be made in various customary ways. They may include, for example, a treadmill.
Dans un mode de réalisation préféré, la chambre de concassage 9 présente une direction de travail D1 entre son entrée et sa sortie, et le crible 14 présente une direction de travail D2 entre son entrée et sa sortie, comme représenté sur la figure 2. Par direction de travail d'une unité quelconque, on entend la direction selon laquelle se déplacent les produits, notamment les agrégats, à l'intérieur de l'unité considérée lors de leur traitement. In a preferred embodiment, the crushing chamber 9 has a working direction D1 between its inlet and its outlet, and the screen 14 has a working direction D2 between its inlet and its outlet, as shown in FIG. work direction of any unit means the direction in which the products, including aggregates, move within the unit under consideration during processing.
Les directions de travail D1 et D2 sont latérales, c'est-à-dire transversales à la direction longitudinale L du châssis 2 de l'engin 1 . En d'autre termes, elles sont inclinées par rapport à cette direction longitudinale L et donc non parallèles à cette dernière. De préférence, les directions de travail D1 et D2 sont sensiblement orthogonales à la direction longitudinale L, comme représenté sur la figure 2. The working directions D1 and D2 are lateral, that is to say transverse to the longitudinal direction L of the chassis 2 of the machine 1. In other words, they are inclined with respect to this longitudinal direction L and therefore not parallel to the latter. Preferably, the working directions D1 and D2 are substantially orthogonal to the longitudinal direction L, as shown in FIG. 2.
De plus, l'engin motorisé 1 comporte une voie de transfert 19 entre la chambre de concassage 9 et le crible 14, et la voie de transfert 15 entre le crible 14 et le dispositif mélangeur 10. Les voies de transfert 19 et 15 présentent chacune une direction de transfert F1 et F2 qui est sensiblement parallèle à ladite direction longitudinale L. In addition, the motorized vehicle 1 comprises a transfer path 19 between the crushing chamber 9 and the screen 14, and the transfer path 15 between the screen 14 and the mixing device 10. The transfer channels 19 and 15 each have a transfer direction F1 and F2 which is substantially parallel to said longitudinal direction L.
Ce mode de réalisation préféré avec une chambre de concassage 9 et un crible 14 travaillant latéralement (directions D1 et D2), associés à des transferts longitudinaux d'agrégats (directions F1 et F2), permet de réduire fortement l'encombrement de la chaîne de traitement 6 montée sur le châssis 2 et ainsi de prévoir un châssis 2 plus court. Ce mode de réalisation préféré
présente de nombreux avantages. Il permet ainsi, notamment, de réduire l'éventuelle gêne occasionnée lors de l'exécution des travaux sur le réseau routier. This preferred embodiment with a crushing chamber 9 and a screen 14 working laterally (directions D1 and D2), associated with longitudinal transfers of aggregates (F1 and F2 directions), can greatly reduce the size of the chain of treatment 6 mounted on the frame 2 and thus to provide a frame 2 shorter. This preferred embodiment has many advantages. It thus makes it possible, in particular, to reduce the possible inconvenience caused during the execution of the works on the road network.
Le dispositif de collecte 7 destiné à ramasser les agrégats à traiter et les amener à la chambre de concassage 9 peut être réalisé de différentes manières. The collecting device 7 intended to collect the aggregates to be treated and to bring them to the crushing chamber 9 can be made in different ways.
Dans un premier mode de réalisation préféré, le dispositif de collecte d'agrégats 7 comprend un dispositif d'aspiration 16, comme représenté sur les figures 1 et 2. Dans ce mode de réalisation, le dispositif d'aspiration 7 comprend, un appareil tel qu'une turbine pour engendrer une dépression dans le tuyau 8 (ou conduite souple) dont l'extrémité libre accède aux agrégats à récupérer pour les aspirer. Dans l'application décrite ci-dessous, le dispositif d'aspiration 7 peut être alimenté en flux d'aspiration par une turbine située sur un système de tranchage placé devant l'engin motorisé 1 . In a first preferred embodiment, the aggregate collecting device 7 comprises a suction device 16, as shown in FIGS. 1 and 2. In this embodiment, the suction device 7 comprises, an apparatus such as a turbine to generate a vacuum in the pipe 8 (or flexible pipe) whose free end accesses the aggregates to recover to suck. In the application described below, the suction device 7 can be supplied with suction flow by a turbine located on a slicing system placed in front of the motorized vehicle 1.
De préférence, le dispositif d'aspiration 16 est positionné au-dessus à la chambre de concassage 9 afin que les agrégats qui sont aspirés par le flux du dispositif d'aspiration puissent descendre directement par gravité dans la chambre de concassage 9. Preferably, the suction device 16 is positioned above the crushing chamber 9 so that the aggregates which are sucked by the flow of the suction device can descend directly by gravity into the crushing chamber 9.
En outre, dans un second mode de réalisation (non représenté), ledit dispositif de collecte 7 comprend un tapis roulant, dans un mode de chargement mécanique. In addition, in a second embodiment (not shown), said collection device 7 comprises a conveyor belt, in a mechanical loading mode.
Par ailleurs, dans un mode de réalisation préféré, la chambre de concassage 9 est configurée pour fonctionner en dépression. La chambre de concassage 9 a pour but de donner aux agrégats la fraction granulométrique recherchée pour fabriquer le mortier. Furthermore, in a preferred embodiment, the crushing chamber 9 is configured to operate in depression. The purpose of the crushing chamber 9 is to give the aggregates the desired particle size fraction for making the mortar.
L'engin motorisé 1 comporte également une unité de pesée (non représentée) pour peser les agrégats concassés entrant dans le dispositif mélangeur 10, afin de connaître leur poids et de pouvoir y ajouter des poids appropriés de liant (ou de ciment) et d'eau (disponibles dans les cuves montrées par la flèche 1 1 ) pour produire, par un malaxage usuel, un mortier présentant les propriétés recherchées.
Ce mortier est distribué à l'arrière 13B de l'engin motorisé 1 à l'aide de la voie de distribution 12 montrée sur les figures 4 et 5. The motorized vehicle 1 also comprises a weighing unit (not shown) for weighing the crushed aggregates entering the mixing device 10, in order to know their weight and to be able to add appropriate weights of binder (or cement) and water (available in the tanks shown by the arrow 1 1) to produce, by a usual mixing, a mortar having the desired properties. This mortar is distributed at the rear 13B of the motorized vehicle 1 with the aid of the distribution channel 12 shown in FIGS. 4 and 5.
La voie de distribution 12 comporte deux vis sans fin 21 et 22 liées l'une à l'autre. La première vis 21 est agencées transversalement à l'axe longitudinal à l'arrière 13B de l'engin motorisé 1 comme représenté sur la figure 4, et elle est alimentée par le mortier produit par le dispositif mélangeur 10. Lors de la rotation de la vis sans fin 21 , illustrée par une flèche B1 , le mortier produit est déplacé dans le sens illustré par une flèche C1 pour aboutir dans la deuxième vis 22. Cette dernière, par sa rotation illustrée par une flèche B2, déplace le mortier dans le sens illustré par une flèche C2. A la sortie de la vis 22, à son extrémité arrière 24, le mortier peut être récupéré dans un bac de récupération 23, comme illustré par une flèche G1 sur la figure 5. The distribution channel 12 comprises two endless screws 21 and 22 connected to each other. The first screw 21 is arranged transversely to the longitudinal axis at the rear 13B of the motorized machine 1 as shown in FIG. 4, and is fed by the mortar produced by the mixing device 10. During the rotation of the worm 21, illustrated by an arrow B1, the product mortar is moved in the direction illustrated by an arrow C1 to end in the second screw 22. The latter, by its rotation illustrated by an arrow B2, moves the mortar in the direction illustrated by a C2 arrow. At the outlet of the screw 22, at its rear end 24, the mortar can be recovered in a recovery tank 23, as illustrated by an arrow G1 in FIG.
Pour permettre d'adapter la position de sortie, à savoir l'extrémité arrière 24 libre de la vis 22 en fonction notamment du positionnement du bac de récupération 23, la vis 22 est articulée, via une articulation usuelle 25, à la vis 21 . Elle peut être déplacée angulairement et adopter une position qui est soit dirigée le long de l'axe longitudinal, soit inclinée latéralement par rapport à cet axe longitudinal. To make it possible to adapt the output position, namely the free rear end 24 of the screw 22 as a function in particular of the positioning of the recovery tank 23, the screw 22 is articulated, via a usual hinge 25, to the screw 21. It can be moved angularly and adopt a position which is either directed along the longitudinal axis, or inclined laterally with respect to this longitudinal axis.
Le bac de récupération 23 est guidé par deux guides dans la tranchée et appuyé à droite et gauche de celle-ci sur deux plaques d'appui. Il est alimenté en mortier par le dessus et alimente par gravité la tranchée T, comme illustré par des flèches G1 , G2 et G3 sur la figure 5. Le bac de récupération 23 est pourvu dans sa partie arrière basse d'un conduit d'évacuation 27. De préférence, le dispositif mélangeur 10 (ou centrale à mortier ou à béton) est configuré pour produire un mortier (ou béton) auto- plaçant, ce qui facilite sa mise en place dans la tranchée T. The recovery tank 23 is guided by two guides in the trench and pressed on the right and left of it on two support plates. It is fed with mortar from above and feeds the trench T by gravity, as illustrated by arrows G1, G2 and G3 in FIG. 5. The recovery tank 23 is provided in its lower rear part with an evacuation duct. 27. Preferably, the mixing device 10 (or mortar or concrete plant) is configured to produce a self-placing mortar (or concrete), which facilitates its placement in the trench T.
Dans le cadre de la présente invention, l'engin motorisé 1 peut être monté sur une semi-remorque ou un camion 8x4 ou sur tout autre engin ou moyen motorisé de chantier, pour transporter l'unité de traitement 6.
L'engin motorisé 1 possède, en outre, un avancement hydrostatique ou électrique capable d'être réglé, de préférence, dans une plage de 0 à 1 km/h. In the context of the present invention, the motorized vehicle 1 can be mounted on a semi-trailer or an 8x4 truck or on any other machine or motorized site means for transporting the processing unit 6. The motorized vehicle 1 further has a hydrostatic or electric advance capable of being adjusted, preferably in a range of 0 to 1 km / h.
L'engin motorisé 1 peut comporter une alimentation électrique par génératrice à aimant continu. The motorized vehicle 1 may include a power supply by a generator with a continuous magnet.
Le fonctionnement de l'engin motorisé 1 mobile, tel que décrit ci- dessus et représenté notamment sur les figures 1 et 2, est le suivant. The operation of the mobile engine 1, as described above and shown in particular in Figures 1 and 2, is as follows.
Des agrégats situés au niveau du sol, soit à l'avant de l'engin motorisé 1 , soit latéralement à l'engin motorisé 1 , sont récupérés, de préférence aspirés, par le dispositif de collecte 7 comme illustré par une flèche H1 sur les figures 1 et 2. Le dispositif de collecte 7 amène ces agrégats dans la chaîne le traitement 6 et plus précisément dans la chambre de concassage 9. Après concassage, les agrégats sont transférés au crible 14 via la voie de transfert 19. Le crible 14 met en œuvre une séparation des agrégats de sorte que les agrégats suffisamment concassés sont transmis au dispositif mélangeur 10 via la voie de transfert 15 comme illustré par les flèches A1 à A4 sur la figure 3, tandis que les agrégats insuffisamment concassés sont renvoyés dans la chambre de concassage 9 via une voie de transfert non représentée. Le dispositif mélangeur 10 mélange les agrégats reçus avec des quantités appropriées d'eau et de liant pour former un mortier. Ce mortier est ensuite distribué à l'arrière de l'engin motorisé 1 , par l'intermédiaire de la voie de distribution 12, via le bac de récupération 23, comme montré sur la figure 5 notamment. Aggregates located at ground level, either at the front of the motorized vehicle 1, or laterally to the motorized vehicle 1, are recovered, preferably aspirated, by the collecting device 7 as illustrated by an arrow H1 on the Figures 1 and 2. The collection device 7 brings these aggregates in the chain treatment 6 and more precisely in the crushing chamber 9. After crushing, the aggregates are transferred to the screen 14 via the transfer path 19. The sieve 14 sets separating the aggregates so that the sufficiently crushed aggregates are transmitted to the mixing device 10 via the transfer path 15 as illustrated by the arrows A1 to A4 in FIG. 3, while the insufficiently crushed aggregates are returned to the chamber of crushing 9 via a transfer channel not shown. The mixing device 10 mixes the received aggregates with appropriate amounts of water and binder to form a mortar. This mortar is then distributed at the rear of the motorized vehicle 1, via the distribution channel 12, via the recovery tank 23, as shown in Figure 5 in particular.
L'engin motorisé 1 , tel que décrit ci-dessus, comprenant une chaîne de traitement 6 qui fabrique en continu du mortier prêt à l'emploi, présente de nombreux avantages. En particulier, il réalise un recyclage efficace, directement sur le chantier, de l'ensemble des agrégats produits, et ceci à l'aide d'un seul et même engin motorisé, ce qui permet d'une part d'éviter les coûts usuels d'évacuation d'agrégats et d'autre part de disposer de mortier sur le chantier. The motorized vehicle 1, as described above, comprising a processing line 6 which continuously manufactures mortar ready for use, has many advantages. In particular, it realizes an effective recycling, directly on the site, of all the aggregates produced, and this with the help of a single motorized vehicle, which allows on the one hand to avoid the usual costs and to dispose of mortar on site.
L'engin motorisé 1 , tel que décrit ci-dessus, peut être utilisé comme système autonome. Dans ce cas, le dispositif de collecte 7, de préférence un
dispositif d'aspiration, collecte les agrégats disposés notamment au sol, à partir de l'avant ou de côté de l'engin motorisé 1 , et les amène à la chaîne de traitement 6, et la chaîne de traitement 6 les transforme en mortier, qui est disponible à l'arrière 13B de l'engin motorisé 1 . A titre d'illustration, les agrégats peuvent être des agrégats générés par un creusage, par exemple d'une tranchée, ou des gravats générés par la démolition d'un ouvrage. The motorized vehicle 1, as described above, can be used as an autonomous system. In this case, the collection device 7, preferably a suction device, collecting the aggregates arranged in particular on the ground, from the front or side of the motorized vehicle 1, and brings them to the processing chain 6, and the processing chain 6 transforms them into a mortar, which is available at the rear 13B of the motorized vehicle 1. By way of illustration, the aggregates can be aggregates generated by digging, for example a trench, or rubble generated by the demolition of a structure.
Dans une application préférée, l'engin motorisé 1 de recyclage d'agrégats, tel que décrit ci-dessus, fait partie d'un ensemble motorisé 30 pour la réalisation de tranchées, comme représenté à titre d'exemple sur la figure 6. In a preferred application, the motorized aggregate recycling machine 1, as described above, is part of a motorized assembly 30 for making trenches, as shown by way of example in FIG.
Cet ensemble motorisé 30 comporte, en plus de l'engin motorisé 1 , un système 31 de réalisation de tranchées dans le sol. Ce système 31 comprend, notamment, un dispositif 32 de creusage de tranchée et un système 33 d'aspiration et de collecte des agrégats produits lors du creusage d'une tranchée par le dispositif 32. Ce système 31 de réalisation de tranchées correspond, de préférence, au dispositif décrit dans le brevet FR-2 822 862. This motorized assembly 30 comprises, in addition to the motorized vehicle 1, a system 31 for producing trenches in the ground. This system 31 comprises, in particular, a trench-digging device 32 and a system 33 for extracting and collecting the aggregates produced during the digging of a trench by the device 32. This trench-making system 31 corresponds, preferably , to the device described in patent FR-2,822,862.
Dans le mode de réalisation représenté sur la figure 6, le système 31 de réalisation de tranchées comporte une unité motrice auxiliaire autonome 34, et il est lié audit engin motorisé 1 de recyclage d'agrégats, comme précisé ci-dessous. In the embodiment shown in FIG. 6, the trenching system 31 comprises an autonomous auxiliary power unit 34, and it is linked to said motorized aggregate recycling machine 1, as specified below.
Le système 31 représenté sur la figure 6 comprend, sur un châssis 35, le dispositif de creusage 32 par roue trancheuse 36 pour réaliser une tranchée T dans le sol S (une route par exemple). Le dispositif de creusage 32 est situé en partie arrière du châssis 35. De façon usuelle, la roue trancheuse 36 est munie à sa périphérie d'organes de coupe. Dans l'exemple illustré, la roue est destinée à réaliser des tranchées étroites et de faible profondeur, notamment pour la pose de câbles (optiques, électriques, téléphoniques, ...). The system 31 shown in Figure 6 comprises, on a frame 35, the digging device 32 trencher wheel 36 to make a trench T in the ground S (a road for example). The digging device 32 is located at the rear of the frame 35. Usually, the trencher wheel 36 is provided at its periphery with cutting members. In the illustrated example, the wheel is intended to make narrow trenches and shallow, especially for laying cables (optical, electrical, telephone, ...).
Dans l'exemple de réalisation représenté, le dispositif d'aspiration et de collecte 33 comprend, un appareil pour engendrer une dépression, tel qu'une turbine, et un carter 37 enveloppant partiellement la roue trancheuse 36. Dans cet exemple de réalisation, la turbine est reliée à l'espace interne entre le
carter 37 et la roue trancheuse 36 par l'intermédiaire d'une conduite souple 8. Cette dernière est raccordée, d'un côté, à une prise d'aspiration ménagée dans le carter 37, et, de l'autre côté, au dispositif de collecte 7 monté sur l'engin motorisé 1 . In the exemplary embodiment shown, the suction and collection device 33 comprises, an apparatus for generating a vacuum, such as a turbine, and a casing 37 partially enveloping the trencher wheel 36. In this embodiment, the turbine is connected to the internal space between the casing 37 and the trencher wheel 36 via a flexible pipe 8. The latter is connected, on one side, to a suction intake formed in the housing 37, and, on the other side, to the device collection 7 mounted on the motorized vehicle 1.
L'engin motorisé 1 utilise les agrégats produits lors du creusage de la tranchée par le système 31 et récupérés via le dispositif 7 de collecte d'agrégats, comme illustré par des flèches J1 et J2, pour fabriquer du mortier. Le mortier produit en sortie du dispositif mélangeur 10, est utilisé de préférence, pour reboucher au moins une partie de la tranchée T creusée par ledit système 31 . The motorized vehicle 1 uses the aggregates produced during digging of the trench by the system 31 and recovered via the device 7 for collecting aggregates, as illustrated by arrows J1 and J2, to manufacture mortar. The mortar produced at the outlet of the mixing device 10 is preferably used for resealing at least part of the trench T dug by said system 31.
Dans le mode de réalisation, représenté sur la figure 6, le dispositif 7 de collecte d'agrégats fait partie dudit dispositif 33 d'aspiration et de collecte. In the embodiment, shown in Figure 6, the aggregate collection device 7 is part of said suction and collection device 33.
L'ensemble motorisé 30 permet ainsi une utilisation des matériaux (gravats) excavés sur site, pour le rebouchage immédiat de la tranchée T par le mortier produit, ce qui génère une optimisation des coûts en logistique et en produit. The motorized assembly 30 thus allows the use of materials (rubble) excavated on site, for the immediate filling trench T by the product mortar, which generates an optimization of logistics and product costs.
Le système 31 comporte également une bobine 38 de câble 39 (fibre optique,...) ou de pipe en PEHD, agencée à l'avant de la cabine de conducteur dudit système 31 . The system 31 also comprises a coil 38 of cable 39 (optical fiber, ...) or HDPE pipe, arranged at the front of the driver's cabin of said system 31.
Le fonctionnement de l'ensemble motorisé 30, tel que décrit ci-dessus, est le suivant. The operation of the motorized assembly 30, as described above, is as follows.
Durant l'exécution de la tranchée, le système 31 peut être entraîné par une transmission hydrostatique alimentant également les différentes servitudes (vérins, moteurs, ...) et permettant d'adapter aisément son avance à la réalisation de la tranchée. During the execution of the trench, the system 31 may be driven by a hydrostatic transmission also supplying the different servitudes (jacks, motors, etc.) and making it possible to easily adapt its advance to the completion of the trench.
De préférence, la tranchée T est réalisée avec la roue trancheuse 36 du dispositif de creusage 32 disposée dans l'axe longitudinal médian du système 31 , orthogonalement au plan du châssis 35. Lors de l'avance du système 31 , via la rotation de la roue trancheuse 36, le dispositif de creusage 32 creuse la tranchée T progressivement. Les agrégats produits par la fouille le long du front de taille sont entraînés vers l'intérieur du carter 36 dont
l'espace interne est en dépression grâce au fonctionnement du dispositif d'aspiration et de collecte 7. Les agrégats sortant du front de taille sont alors aspirés en direction de la chaîne de traitement 6 de l'engin motorisé 1 . Preferably, the trench T is made with the trencher wheel 36 of the digging device 32 arranged in the median longitudinal axis of the system 31, orthogonal to the plane of the frame 35. During the advance of the system 31, via the rotation of the trencher wheel 36, the digging device 32 digs the trench T gradually. The aggregates produced by the excavation along the cutting face are driven towards the inside of the casing 36 of which the internal space is in depression due to the operation of the suction and collection device 7. The aggregates leaving the cutting face are then sucked towards the processing line 6 of the motorized vehicle 1.
Simultanément au creusage de la tranchée T, le câble ou pipe 39, en particulier un faisceau de fibres optiques, est déroulé (comme illustré par des flèches 11 , 12 et 13) d'une bobine 38 agencée à l'avant du système 31 , à l'aide de moyens usuels. Ce câble ou pipe 39 passe au-dessus du système 31 et est posé en aval de la roue trancheuse 36, entre cette dernière et l'engin motorisé 1 , dans la tranchée T. Simultaneously with the digging of the trench T, the cable or pipe 39, in particular a bundle of optical fibers, is unwound (as illustrated by arrows 11, 12 and 13) of a coil 38 arranged at the front of the system 31, using usual means. This cable or pipe 39 passes over the system 31 and is placed downstream of the trencher wheel 36, between the latter and the motorized vehicle 1, in the trench T.
Quant aux agrégats récupérés dans la chaîne de traitement 6, comme illustré par les flèches J1 et J2, ils sont traités de la manière précisée ci- dessous en référence aux figures 1 et 2, pour produire du mortier. Ce mortier est finalement utilisé à l'arrière de l'engin motorisé 1 pour combler la tranchée T. As for the aggregates recovered in the processing chain 6, as illustrated by the arrows J1 and J2, they are treated in the manner specified below with reference to Figures 1 and 2, to produce mortar. This mortar is finally used at the rear of the motorized vehicle 1 to fill the trench T.
Dans ce mode de réalisation, le système 31 et l'engin motorisé 1 se déplacent à la même vitesse, l'un derrière l'autre, dans le sens indiqué par la flèche E sur la figure 6. In this embodiment, the system 31 and the motorized vehicle 1 move at the same speed, one behind the other, in the direction indicated by the arrow E in FIG.
De préférence, l'ensemble motorisé 1 comporte un moyen (par exemple un radar ou tout autre moyen possible) d'asservissement de la vitesse d'avancement des deux systèmes : du système 31 et de l'engin motorisé 1 . Preferably, the motorized assembly 1 comprises a means (for example a radar or any other possible means) for controlling the speed of advance of the two systems: the system 31 and the motorized vehicle 1.
Dans une variante de réalisation (non représentée), l'ensemble motorisé comporte, en plus de l'engin motorisé, un système de réalisation de tranchées dans le sol, mais pas de système d'aspiration et de collecte des agrégats tel que le système 33 précité. Dans cette variante de réalisation, le dispositif 7 de collecte d'agrégats (de l'engin motorisé 1 ) est de type mécanique, par exemple une pelle ou un engin télescopique ou autre, et il est configuré pour collecter par voie mécanique les agrégats générés par le système de réalisation de tranchées. In an alternative embodiment (not shown), the motorized assembly comprises, in addition to the motorized machine, a system for producing trenches in the ground, but no suction system and collection aggregates such as the system 33 cited above. In this variant embodiment, the device 7 for collecting aggregates (of the motorized vehicle 1) is of the mechanical type, for example a shovel or a telescopic machine or the like, and it is configured to mechanically collect the aggregates generated. by the trenching system.
Par ailleurs, dans autre une variante de réalisation (non représentée), le système 31 de réalisation de tranchées peut être monté sur le châssis 2 de
l'engin motorisé 1 de recyclage d'agrégats. Dans cette variante de réalisation, l'ensemble des moyens (systèmes, dispositifs,...) pour la réalisation des tranchées et le recyclage des agrégats, est monté sur un seul et même engin motorisé. Moreover, in another variant embodiment (not shown), the trenching system 31 can be mounted on the chassis 2 of the motorized machine 1 for recycling aggregates. In this variant embodiment, all the means (systems, devices, etc.) for producing the trenches and recycling the aggregates are mounted on one and the same motorized vehicle.
L'ensemble motorisé 30, tel que décrit ci-dessus, présente de nombreux avantages, et en particulier : Motorized assembly 30, as described above, has many advantages, and in particular:
- une économie de granulats naturels, pour produire du mortier ; - economy of natural aggregates, to produce mortar;
- une réduction importante des coûts logistiques (l'évacuation des agrégats et l'approvisionnement en mortier étant supprimés) ; et - a significant reduction in logistics costs (the disposal of aggregates and the supply of mortar being removed); and
- une réduction des coûts de main-d'œuvre. - a reduction in labor costs.
L'ensemble motorisé 30 génère ainsi une optimisation des coûts pour la construction de réseaux, tout en améliorant l'impact environnemental.
The motorized assembly 30 thus generates cost optimization for the construction of networks, while improving the environmental impact.
